IMPROVEMENT in sTovE-PIPE DRUMS.

Specification forming part of Letters Patent No. 47,833, dated May23,1865.

.To all whom it may concern:

Be it known that I, JACOB B. HYZER, of the city oit' Janesville, countyof Rock, and Sta-te of Wisconsin, have invente l a new and ImprovedInode of' Constructing and Uperating a Heat-Radiator; and I do herebydeclare that the followingis a full, clear, and exact descript-ion ofthe construction and operation of the same, reference being had to theaccompanying drawings, making a part of this specication, likecharacters referring to like parts in each figure.

The nature of my invention consists, rst, in making a series of'holesthrough the radial plates used to partition heat-radiators, to partiallyturn the draft so that all parts ot1 the radiating-surfaces are equallyheated and radiate the same amount of heat; second, in so constructing aheat-radiator having ascending aud descending flues ory an innerunconrined hot-air space that one central pipe and a'i ordinary damperserve all the purpose of inducting and discharging the smoke and iiame.

To enable others skilled in the mechanic arts to construct and operate aheat-radiator with my improvement, I will refer to the accompanyingdrawings, in which- Figure lis an elevation with a portion of the outercylinder or case broken away. Fig. 2 is a vertical section cut centrallyon the line ot' the damper-rod. Fig. 3 is a vertical section at rightangles to Fig. 2. Fig. fl is a plan or top view or" the heat-radiator.Fig. 5 is a vertical section with a portion oi' the upper part cut away)similar to Fig. 3, showing a modification ofthe cross-fines and dampers.

I construct the radiator ot1 any convenient form or size, and from anysuitable material, providing it with the appendages heretofore used-4towit, an outer and an inner radiatingcylinder, A B, radial plates a anda', and an inner unconned hot-a-ir space, f. Centrally through thehot-air space j', I pass the smokeflue C, from opposite sides of whichthe crossiiues d and e are made to pass through the lower portion of thecylinder B into the space g between it and the outer case. When thecross-dues d and e are placed with reference to their altitude directlyopposite to each other, as shown in Fig. 3, a damper bent in the formtherein shown is required; but when the :dues

d and e are placed one above the other, as shown in Fig. 5, I use theplain straight damper therein shown.

In the space g between the cylinders, midway between the cross iiues, Iput the radial plates a and a', partitioning the lower portion of thespace, so that the heated air, flame, and smoke, dividing as they enterthrough the iiue d, must pass upward to the top of the radiator and overthe radial plates a and a', and thence downward and through the iiue einto the central pipe, C, again. In the radial plates I make a series ofholes or orifices, a, the objectof which is to allow enough of theheated air, smoke, and flame to pass through the radial plates toheatthose portions of the radiatingcylinders adjacent to the lowerportions of thc plates, and so preventing the radiating-cylinders frombeing' unevenly heated, as heretofore experienced.

When in operation, turning the damper c to the position shown by thedotted lines c', Figs. 2, 3, and 5, secures `a straight, direct,

and full draft; but with it in the position shown in the drawings, theheated air, smoke, and flame pass through the lue'd into the spacebetween the radiating-cylinders A B, thence over or through the radialplates a and a to the opposite side of the space, and thence through theflue e into the smoke-pi pe C, above the damper.

It will be seen that a radiator constructed as above described, with theinductive and discharge pipes forming one and the same iiue, secures thefull draftof the ordinary pipe when desired, requires only one plain,cheap damper, and does not need to be supported, as the induction-pipeentering the radiator centrally from below supports it, thus avoidingthe cost of constructing and the inconvenience of operating two dampers,and the difficulty of supporting the radiator'when the induction-pipedoes not enter it centrally from below.

I apply my radiator both to furnaces andstoves. h

I am aware that ascending and descending iiues and an inner hot-airspace, as also a straight flue regulated by a single damper, (to wit,the ordinary stove-pipe and dan1per,) have heretofore been known andused, and I do not claim them when used separately, but

only when combined as hereinbefere deseriba straight flue regulated by asingle damper,

ed; but' substantially as described.
